Jabster,
check out this thread:
Larger Wheels FAQ has a lot of info on what fits and what doesn't. as well as some pictures.
pretty much all of the topics that aren't really general Sequoia questions will be in the specific topical forums. it will take a little getting used to, but it's the best way to get the most info and responses from our members.
btw, all of my mods can be seen on my www
